closes https://github.com/TryGhost/Team/issues/1916 closes https://github.com/TryGhost/Team/issues/1917 - Added database storage for link redirects and click events via repositories (hides away database layer) defined in the wrapper services - Added LinkClickRepository to store click events to database - Added LinkRedirectRepository to store link redirects to database - Added PostLinkRepository to link LinkRedirects with posts - Renamed link-replacement package to link-replacer, and made it dependency less (it only replaces links now, doesn't do anything else) - The link-tracking service has a new `addTrackingToUrl` which returns a new URL that includes tracking. The new `addRedirectToUrl` method does the same but without tracking for now. - MEGA service now uses the link-replacer to replace links in the emails using a combination of different services (member attribution + link-tracking service)
